Backwards Incompatible Changes
==============================
Despite our best efforts, sometimes the OpenStackClient team may introduce a
backwards incompatible change. For user convenience we are tracking any such
changes here (as of the 1.0.0 release).
Should positional arguments for a command need to change, the OpenStackClient
team attempts to make the transition as painless as possible. Look for
deprecation warnings that indicate the new commands (or options) to use.
Commands labeled as a beta according to :ref:`command-beta` are exempt
from this backwards incompatible change handling.
Backwards Incompatible Changes
==============================
.. Carry this section as comments until 4.0 release
.. Release 4.0
.. -----------
.. 1. Change ``volume transfer request accept`` to use new option ``--auth-key``
.. rather than a second positional argument.
.. * As of: 4.0
.. * Remove in: <5.0>
.. * Commit: <tbd>
Release 3.12
------------
1. Replace ``Display Name`` by ``Name`` in volume list.
Change column name ``Display Name`` to ``Name`` in ``volume list`` output.
Current ``volume list --name`` command uses ``display_name`` as search_opts
to send to cinder API, and show the result table with ``Display Name``
as column title. Replace all ``Display Name`` by ``Name`` to be consistent
with other list commands.
Support a mapping for volume list -c ``Display Name`` (Volume v1 and v2)
and volume create/show -c ``display_name`` (Volume v1) to maintain backward
compatibility until the next major release.
* In favor of: ``openstack volume list -c Name``
* As of: 3.12.0
* Removed in: n/a
* Bug: https://bugs.launchpad.net/python-openstackclient/+bug/1657956
* Commit: https://review.openstack.org/#/c/423081/
Release 3.10
------------
1. The ``network create`` command now requires the ``--subnet`` option when used
with Nova-network clouds.
* As of: 3.10
* Commit: https://review.openstack.org/460679
2. The positional argument ``<snapshot-name>`` of the ``volume snapshot create``
command is no longer optional.
Previously when the ``--volume`` option was
present ``<snapshot-name>`` defaulted to the ``--volume`` value. When the
``--volume`` option is not present now it defaults to the value of
``<snapshot-name>``.
* As of: 3.10
* Bug: 1659894
* Commit: https://review.openstack.org/440497
Release 3.0
-----------
1. Remove the ``osc_password`` authentication plugin.
This was the 'last-resort' plugin default that worked around an old default
Keystone configuration for the ``admin_endpoint`` and ``public_endpoint``.
* In favor of: ``password``
* As of: 3.0
* Removed in: n/a
* Bug: n/a
* Commit: https://review.openstack.org/332938
Releases Before 3.0
-------------------
1. Rename command `openstack project usage list`
The `project` part of the command was pointless.
* In favor of: `openstack usage list` instead.
* As of: 1.0.2
* Removed in: TBD
* Bug: https://bugs.launchpad.net/python-openstackclient/+bug/1406654
* Commit: https://review.openstack.org/#/c/147379/
2. <type> should not be optional for command `openstack service create`
Previously, the command was `openstack service create <name> --type <type>`,
whereas now it is: `openstack service create <type> --name <name>`.
This bug also affected python-keystoneclient, and keystone.
* In favor of: making <type> a positional argument.
* As of: 1.0.2
* Removed in: TBD
* Bug: https://bugs.launchpad.net/python-openstackclient/+bug/1404073
* Commit: https://review.openstack.org/#/c/143242/
3. Command `openstack security group rule delete` now requires rule id
Previously, the command was `openstack security group rule delete --proto
<proto> [--src-ip <ip-address> --dst-port <port-range>] <group>`,
whereas now it is: `openstack security group rule delete <rule>`.
* In favor of: Using `openstack security group rule delete <rule>`.
* As of: 1.2.1
* Removed in: NA
* Bug: https://bugs.launchpad.net/python-openstackclient/+bug/1450872
* Commit: https://review.openstack.org/#/c/179446/
4. Command `openstack image create` does not update already existing image
Previously, the image create command updated already existing image if it had
same name. It disabled possibility to create multiple images with same name
and lead to potentially unwanted update of existing images by image create
command.
Now, update code was moved from create action to set action.
* In favor of: Create multiple images with same name (as glance does).
* As of: 1.5.0
* Removed in: NA
* Bug: https://bugs.launchpad.net/python-openstackclient/+bug/1461817
* Commit: https://review.openstack.org/#/c/194654/
5. Command `openstack network list --dhcp` has been removed
The --dhcp option to network list is not a logical use case of listing
networks, it lists agents. Another command should be added in the future
to provide this functionality. It is highly unlikely anyone uses this
feature as we don't support any other agent commands. Use neutron
dhcp-agent-list-hosting-net command instead.
* In favor of: Create network agent list command in the future
* As of: 1.6.0
* Removed in: NA
* Bug: https://bugs.launchpad.net/python-openstackclient/+bug/472613
* Commit: https://review.openstack.org/#/c/194654/
6. Plugin interface change for default API versions
Previously, the default version was set in the parsed arguments,
but this makes it impossible to tell what has been passed in at the
command line, set in an environment variable or is just the default.
Now, the module should have a DEFAULT_API_VERSION that contains the
value and it will be set after command line argument, environment
and OCC file processing.
* In favor of: DEFAULT_API_VERSION
* As of: 1.2.1
* Removed in: NA
* Bug: https://bugs.launchpad.net/python-openstackclient/+bug/1453229
* Commit: https://review.openstack.org/#/c/181514/
7. `image set` commands will no longer return the modified resource
Previously, modifying an image would result in the new image being displayed
to the user. To keep things consistent with other `set` commands, we will
no longer be showing the modified resource.
* In favor of: Use `set` then `show`
* As of: NA
* Removed in: NA
* Bug: NA
* Commit: NA
8. `region` commands no longer support `url`
The Keystone team removed support for the `url` attribute from the client
and server side. Changes to the `create`, `set` and `list` commands for
regions have been affected.
* In favor of: NA
* As of 1.9.0
* Removed in: NA
* Bug: https://launchpad.net/bugs/1506841
* Commit: https://review.openstack.org/#/c/236736/
9. `flavor set/unset` commands will no longer return the modified resource
Previously, modifying a flavor would result in the new flavor being displayed
to the user. To keep things consistent with other `set/unset` commands, we
will no longer be showing the modified resource.
* In favor of: Use `set/unset` then `show`
* As of: NA
* Removed in: NA
* Bug: https://bugs.launchpad.net/python-openstackclient/+bug/1546065
* Commit: https://review.openstack.org/#/c/280663/
10. `security group set` commands will no longer return the modified resource
Previously, modifying a security group would result in the new security group
being displayed to the user. To keep things consistent with other `set`
commands, we will no longer be showing the modified resource.
* In favor of: Use `set` then `show`
* As of: NA
* Removed in: NA
* Bug: https://bugs.launchpad.net/python-openstackclient/+bug/1546065
* Commit: https://review.openstack.org/#/c/281087/
11. `compute agent set` commands will no longer return the modified resource
Previously, modifying an agent would result in the new agent being displayed
to the user. To keep things consistent with other `set` commands, we will
no longer be showing the modified resource.
* In favor of: Use `set` then `show`
* As of: NA
* Removed in: NA
* Bug: https://bugs.launchpad.net/python-openstackclient/+bug/1546065
* Commit: https://review.openstack.org/#/c/281088/
12. `<version> <url> <md5hash>` should be optional for command `openstack
compute agent set`
Previously, the command was `openstack compute agent set <id> <version> <url>
<md5hash>`, whereas now it is: `openstack compute agent set <id> --version
<version> --url <url> --md5hash <md5hash>`.
* In favor of: making <version> <url> <md5hash> optional.
* As of: NA
* Removed in: NA
* Bug: NA
* Commit: https://review.openstack.org/#/c/328819/
13. `aggregate set` commands will no longer return the modified resource
Previously, modifying an aggregate would result in the new aggregate being
displayed to the user. To keep things consistent with other `set` commands,
we will no longer be showing the modified resource.
* In favor of: Use `set` then `show`
* As of: NA
* Removed in: NA
* Bug: https://bugs.launchpad.net/python-openstackclient/+bug/1546065
* Commit: https://review.openstack.org/#/c/281089/
14. Output of `ip floating list` command has changed.
When using Compute v2, the original output is:
.. code-block:: bash
# ip floating list
+----+--------+------------+----------+-------------+
| ID | Pool | IP | Fixed IP | Instance ID |
+----+--------+-----------------------+-------------+
| 1 | public | 172.24.4.1 | None | None |
+----+--------+------------+----------+-------------+
Now it changes to:
.. code-block:: bash
# ip floating list
+----+---------------------+------------------+-----------+--------+
| ID | Floating IP Address | Fixed IP Address | Server ID | Pool |
+----+---------------------+------------------+-----------+--------+
| 1 | 172.24.4.1 | None | None | public |
+----+---------------------+------------------+-----------+--------+
When using Network v2, which is different from Compute v2. The output is:
.. code-block:: bash
# ip floating list
+--------------------------------------+---------------------+------------------+------+
| ID | Floating IP Address | Fixed IP Address | Port |
+--------------------------------------+---------------------+------------------+------+
| 1976df86-e66a-4f96-81bd-c6ffee6407f1 | 172.24.4.3 | None | None |
+--------------------------------------+---------------------+------------------+------+
* In favor of: Use `ip floating list` command
* As of: NA
* Removed in: NA
* Bug: https://bugs.launchpad.net/python-openstackclient/+bug/1519502
* Commit: https://review.openstack.org/#/c/277720/
